Re: Gfa init a high res Truecolor or 256c mode on falcon

@shoggoth; I may be out on thin ice here but if I add up the bits value in the first result (434 dec for st-low) it makes sense, if I discard the upper word it would equal 434-256 or am I totally wrong? Still wonder why i get different results from the first read when all i do is read :/ Ahem, and I...

Re: Gfa init a high res Truecolor or 256c mode on falcon

Will try later when i get home, but if the upper word is dropped you'll miss the doubleline bit no? I've seen that the bits 2-8 (or 1-7 i dont know wich is the right way to count :)) are reserved so i guess that it is there the garbage is showing up.. Thanks anyhow, it"s not that important but ...

Re: Gfa init a high res Truecolor or 256c mode on falcon

I just save the modecode to a variable the same way I've seen in all examples mode%=XBIOS(88,-1) Then i print the value to screen and first time i get the correct decimal value (434 if in st-low for example). I tried this too for i=0 to 10 mode%=(xbios(88,w:-1)) print mode% next i First one is actua...

Re: Gfa init a high res Truecolor or 256c mode on falcon

Sorry for reviving an old thread but sort of on topic :? Shouldn't VsetMode (or xbios(88)) return the same value every time i inquire it (without changing the resolution of course) ? If i save it more than once, the second time and beyond it returns a value ten times a word?? (Second and on stays th...

N00b question but just out of curiosity when there seems to be a problem with reset circuit, the piggyback CAP isn't necessary?

Just a thought :)

Re: DIY: new cell for NVRAM chip

Hi! I've got some free samples of the Dallas 12887A from maxim, but I noticed there are fewer pins on these? Made me a bit insecure =).. Also, I've lended a solderstation from work to do the switch, because my own 15w iron does'nt get warm enough it seems. What temperature should I have? Regards /Da...

You could probably use Smurf (http://home.ewr-online.de/~gstoll/0a.htm) to convert to pi3 i think :)

Re: GFA - how to load GIF, PNG, IMG... 256 color picture

Hello. I have also tried the above but eperimented with the resolution.
I can't really get why, if I set res to 640*480*8bp (&X111011)(VGA) I get the same image twice
and it looks smaller than the original 320*240.. Anyone got any ideas?

Re: Did I kill my Falcon?

Wongck, thanks a lot! I finally got it to work :) but i did'nt solder, i just twisted the cable so pin 10 from the controller went to pin 12 on the fdd and vice versa and it works like a charm :)

Re: Did I kill my Falcon?

Ok, I've got hold of an pc motherboard for the floppy interface, but there is a ground-pin(5) missing, does it matter?
I'm not too keen on soldering so I don't want to do something I will regret :-)
